What is a Biogas Plant?

A biogas plant is a system that breaks down organic waste without oxygen. This process is called anaerobic digestion. Bacteria inside a sealed digester tank feed on the waste and produce biogas as a result.

Biogas is a mix of methane (CH4) and carbon dioxide (CO2). The methane makes it a useful fuel. Raw biogas contains about 55% to 65% methane. After purification, the methane level rises to 90% or higher. At that point, it becomes Bio CNG or compressed biogas (CBG).

Key Government Schemes Supporting CBG Biogas in India

India backs its biogas sector through a mix of central and state-level incentives. The SATAT scheme guarantees CBG entrepreneurs assured offtake by Oil Marketing Companies at ₹46/kg, aiming for 5,000 CBG plants by 2028. On the household side, the MNRE National Biogas Programme provides subsidies of ₹7,000-₹12,000, varying by state and category.

The GOBARdhan Scheme further supports rural biogas adoption by linking cattle waste management with energy production. Many states layer on additional capital subsidies of 20-40%, while commercial biogas plants benefit from 80% accelerated depreciation in their first year under the Income Tax Act.

How to Choose the Right Compressed Biogas Plant Size?

Picking the right plant size depends on three things: how much waste you produce, what type of waste it is, and what you plan to do with the biogas.

Step 1: Measure Your Daily Waste

Step 2: Know Your Waste Type

Step 3: Decide Your End Use

Applications of Biogas Plants

Biogas plants serve many industries across India. Here are the most common uses.

Waste-to-Energy Projects

Municipalities and private developers set up biogas plants to convert city waste into clean energy. The biogas powers generators or gets upgraded to Bio CNG for vehicle fuel. As a bio gas manufacturing plant supplier in India, we support waste-to-energy projects from 10 TPD to 400 TPD.

Compressed Bio CNG and CBG Production

Biogas plants are the first step in Bio CNG production. The plant produces raw biogas. A purification plant upgrades it to 90%+ methane. A compressor presses it to 250 bar. CNG cascades store it for transport or dispensing. We supply every part of this chain: biogas plant, purification plant, and CNG Cascades for CBG Biogas Plant.

Farm and Dairy Energy

Dairy farms and cattle sheds use biogas plants to turn animal waste into fuel. The biogas runs generators for on-site power. The digestate returns to the fields as organic fertilizer. Small farms start at 6 TPD. Large dairy operations go up to 30 TPD or more.

Industrial Fuel Replacement

Factories replace diesel and LPG with biogas or Bio CNG for boilers, furnaces, and heating. The switch cuts fuel costs and reduces carbon emissions. A biogas plant on the factory premises creates a self-sufficient fuel source from the factory's own organic waste.

SATAT Scheme Projects

The Government of India's SATAT initiative encourages entrepreneurs to set up CBG plants and sell compressed biogas to Oil Marketing Companies (OMCs) like IOCL, BPCL, and HPCL. A biogas plant with downstream purification and compression is the core of every SATAT project. We supply the complete equipment chain.

Power Generation

Biogas runs gas engines and generators to produce electricity. Our 100 kW biogas power generation plant uses a trusted Cummins genset at 415 V. It suits farms, food plants, and municipal facilities that want on-site power from waste.

Organic Fertilizer Production

Every biogas plant produces digestate as a by-product. This nutrient-rich slurry works as organic fertilizer. Some operators process and sell the digestate as a separate revenue stream, adding a second income to the biogas project.

Biogas Plant and Bio CNG: The Full Value Chain

A biogas plant alone produces raw biogas. To turn it into Bio CNG or CBG, you need three more steps after the biogas plant.
Biogas Purification > Compression > Cascade Storage and Transport
